When was the last time anyone got a RUC to instantly clear? It seems it is not even a thing anymore. Applied today with all of FC open on one and only 2 seats shown taken. Neither instantly clears.
Now of course they could be 'sold out' and people haven't selected seat. Did dummy booking and get same amount of seats available as shown via the buy-up offer.
Interesting to see if anyone has had them actually instantly clear. Seems easier to do that with GUCs on partner airlines.
